Description
Technical field
The invention belongs to functional high molecule material preparing technical field, more particularly to a kind of system of efficiently hydrophobic oil suction sponge
Preparation Method.The sponge can be automatical and efficient realize water-oil separating sponge, be crude oil pollution seawater and oil-containing industrial water
Purification provides cheap scheme.
Background technology
Surface/interface property of the repeatable 3 D stereo water-oil separating material utilized based on super oleophylic-super-hydrophobic, can
Efficiently, the oil/water mixture of stratiform is automatically realized into separation, it might even be possible to oil-water separation emulsion, including Water-In-Oil and
Oil-in-water emulsion.Three-dimensional water-oil separating material can realize automatic absorbing oil body, and water body is repelled, therefore without contaminated water
The collection of body, there is the characteristics of quick, efficient, energy-saving and environmental protection.Polluted seawater caused by oil-containing industrial water and crude oil leakage is anxious
It is essential and wants the breakthrough and development of such material.Traditional oily water separation technique mainly includes gravitational separation process, filtration method, centrifugation point
The methods of from method, FLOTATION SEPARATION；The means of use predominantly use oil suction barrier, large-scale oil water separator and vacuum soil pick-up
Car, but these technologies produce little effect since it is desired that collect contaminated seawater and time consuming.The super super-hydrophobic 3 D stereo of oleophylic
Material, can be efficiently to realize water-oil separating, therefore developing intellectual resource type water-oil separating material, energy without collecting contaminated seawater
It is enough the emergent barrier of ecological environment fast construction, will be minimized similar to the ecology influence that disaster is brought.China possesses ocean face
3,000,000 square kilometres of product, more there is Bohai Sea Gulf and two, North Sea semi-closed bay, and exchange of seawater rate is low, once by dirt
Dye, it is difficult to the self-cleaning ability for relying on ocean is recovered, caused by environment influence it is more serious and permanent.Therefore carry out super close
The research of oil-super-hydrophobic 3 D stereo water-oil separating material, the crude oil leakage that being advantageously used for reply may occur at any time are brought
Ocean disaster.3 D stereo hydrophobic oleophilic oil sponge of the present invention can be automatical and efficient realize water-oil separating, be
The purification of crude oil pollution seawater and oil-containing industrial water provides cheap scheme.
